Digital AVC
DESCRIPTION
The Teledyne Hastings Instruments (THI) Digital AVC (DAVC)
is a microprocessor controlled vacuum gauge meter without
readout. In addition to the analog output (0-1 VDC), pressure
measurements can be accessed by an RS232 serial port using
Torr, mbar or Pa.
A precision A/D converter along with the microprocessor
measures the thermocouple vacuum gauge tube’s signal output,
converts the measurement to a pressure reading employing
the gauge tube’s well-defined output/pressure function,
and transmits the result.
These instruments are packaged in a small extruded aluminum
case with controls and D-connector mounted on the top cover.
The Digital AVC Vacuum Gauge Meter is available for three of
THI’s most popular gauge tube families: the DV-6, DV-5 and
the DV-4. The DV-6 range is 1-999 mTorr. The DV-5 range is
0.1-100 mTorr. The DV-4 range is 0.02-20 Torr.
These tubes utilize THI’s rugged but sensitive noble metal
thermocouples that are designed specifically for each range.
Tubes are matched and are interchangeable without calibration
adjustments. They are compensated for temperature and rate
of temperature change and are corrosion resistant.
